R&D Team Lead

Your role and responsibilities

In this role, you will have the opportunity to gain vocational experience through a temporary work placement (6 months). Each day, you will acquire knowledge by performing tasks as directed. You will also showcase your expertise by supporting ABB’s operations and enhancing personal education/employment opportunities.DC microgrids are low-voltage DC networks designed to connect and manage various energy sourcesand consumption devices that inherently use DC voltage, such as photovoltaic systems, batterystorage, electronic loads, electric vehicles, etc. A key challenge in operating DC microgrids is maintaining the DC voltage within certain predefined limits while ensuring the stability of the microgrid. The goal of this thesis is to investigate and design control techniques for DC/DC converters that can achieve DC voltage stabilization and desired load sharing between the available source converters. The work model for the role is: on-site {Linkedin #Onsite}This role is contributing to the Corporate Research Center, Industrial Solutions department in the Power Electronics System group in Baden-Dättwil, Switzerland.The Master’s thesis tasks will consist of the following:• Perform a literature review on existing grid-forming control methods in DC microgrids• Analyze DC bus voltage regulation performance of existing methods by investigating their output impedance properties • Perform passivity analysis to uncover stability characteristics of the existing methods• Based on the performed analysis propose ways to improve the existing designs • Develop a coordinated control design for a set of heterogeneous converters to provide a desired aggregate grid-forming response • Summarize research findings in a reportYou will join a dynamic and high-performing team, where you will be able to thrive.
